When I have the heater on, the harder I press the accelerator, the less power the heater fan gets..... or it kinda sounds like the hot air is getting sucked back and blowing elsewhere. Whats up with that? its been like that since the RB25 was dropped in. The mechanic took the air con out when he put the RB25 in... anything to do with that maybe? (also, was he meant to take that out?? I have no idea how an air con system works, I just assumed I couldnt have it with the RB25 for some reason?) and sometime when I press the brakes, the clock goes really dim...

check all the one-way valves are there and working and also that the vacuum ball is still connected.

Mine did that too. Turned out to be a split in the hose going to the vacuum ball. Thats strange about the brakes, especially considering the only electrical connection they have is the low fluid sensor!

the clock will go dim and ull prob find ur parkers also go on, normal vl elec problem lol
